Static analysis tools for PHP in a single docker image

As part of my job I often perform application reviews and code quality analysis for clients who wish to have their
code base looked at by an independent company. Running static analysis tools is usually a starting point to
the review as it gives a general overview of a state of the project.
I also like to run those tools as part of an introduction to an inherited code base.

For an easy access to the most popular static analysis tools for PHP I recently
created a docker image - phpqa.
Currently it comes with the following tools:

Depending on the requirements of the project being reviewed, it's often needed to customise the image further
with additional PHP extensions or other kinds of dependencies.
In such scenarios I simply create a new image based off jakzal/phpqa
(see the docs for more).
